3. support from Safexpert
Safexpert supports you at various points when switching to the new standard:
3.1 New functionalities in the Safexpert risk assessment
Annex A of EN ISO 13849-1:2023 now provides assistance in determining the parameter P (possibility of avoiding or limiting damage). One parameter (A, B, C) is determined for each of five factors (including the speed at which the hazardous situation occurs). Depending on the frequency of occurrence of parameters A, B or C, the parameter P1 (avoidance possible under certain conditions) or P2 (avoidance hardly possible) is determined.
Figure 1: Excerpt from the function for calculating the "possibility of avoidance"
The new help for determining the parameter P has already been taken into account in the version Safexpert Version 9.0 SP3
Whether the new functionality is offered in your projects depends on the "time of commercialisation" defined in the project. This ensures that the new standard is only applied to those projects whose date of placing on the market is after 31 May 2026.
Interfaces to other systems Safexpert's interfaces to the DGUV's Sistema software and to the TIA Selection Tool from Siemens will of course remain functional. .
3.2 Support through templates and templates in Safexpert
Different templates help you to fulfil your duties more quickly, easily and conveniently:
Safexpert contains numerous free cross-reference lists to standards in the expert field of "Safety of machinery" (ICS circle 13.110), including EN ISO 13849-1:2023.
Cross-reference lists offer the advantage that you can directly see which standards are available for eliminating specific hazards during the risk assessment (see illustration).

Machinery safety standards package
The Machinery safety standards package contains A and B standards that are particularly important for machine, plant and control engineering, including EN ISO 13849-1 in full text. These standards already contain inbuilt link destinations so that you can jump directly from an applied section to the right place in the PDF.
Users of Safexpert with a licenced standards package will receive the amended standard (as soon as the German version is available) free of charge as part of the maintenance contract.
The document comparison provides you with a comparison of the predecessor standard with its successor and allows you to see directly which sections have been changed, deleted or added. The respective sections can be opened in full text for a comparison.

3.3 Further assistance
Free assignment table: If you would like to get an overview of the changes now, we have put together an overview table based on the English-language editions of the standards. This allows you to see the extent to which sections of the 2015 standard have been amended, deleted or new sections added in the 2023 edition.
